Arnold explores the property of the gravitational field (or any

field through a surface is proportional to the solid angle it subtends. For a closed surface, the total flux is Ángulo sólido – Arnold 2.2.3

This write-up covers section ("Solid Angle") from V.I. Arnold’s Mathematical Methods of Classical Mechanics . In this section, Arnold provides a geometric interpretation of Newton's potential using the concept of solid angle, leading to a simplified understanding of Gauss's Theorem .
